I was looking for a way to introduce a short delay after SGP changes the brightness level of the flat panel but before it takes the first flat. I didn’t see that anywhere but that doesn’t mean I didn’t miss it either.
I’m using a Spike-A Flat panel with the Alnitak Emulator. On occasion I’ve noticed that the first flat frame taken for a given filter is completely saturated (65535). The second frame is always fine. Of course, this doesn’t happen all the time or on every filter, but it happens often enough. My thought was maybe the panel occasionally needs 500ms or so after the brightness has changed to allow it to settle.
